Choosing between the LG C3 OLED TV and the Samsung QN90A LCD TV comes down to a few important considerations: The LG C3 offers superior contrast and black levels, making it exceptional for watching movies and ideal for viewing in dark rooms. It also has a wider viewing angle, which is great for gatherings. The Samsung QN90A shines in bright-room viewing due to its higher brightness capabilities. If you watch a lot of TV during the day in a sunny room, this might be the better option. Moreover, while it's also good for gaming, it may not match the LG C3's performance in this area. Both are premium-priced, offering high-quality experiences with subtle differences in performance and suitability for different viewing environments. Give Feedback
